I’m a newb to suppressors. I currently have a SOCOM Mini 2 5.56 which I use on an 18” Douglas Barrel.

The muzzle device is the SF muzzle brake with the labyrinth seals. One thing I’ve noticed is that there is a lot of carbon build up at the flared end of the brake that is past the seals. I’ve had my can stuck a couple times within maybe 100ish rounds. I’ve also noticed carbon deposits on the front of the rail and rear of the can. Yes, it is on correctly, as tight as I can possibly make it, and a check is done before shooting to ensure it is properly engaged.

I know I can take the can off when it’s still hot and that minimizes the sticking issues, but I’m also a creature of habit; once it’s on there, it’s on there (this can is dedicated to this rifle).

My question: are the labyrinth seals really all that important and do they really accomplish anything?

I need to purchase a few more muzzle devices and have the choices set to either the SF CTN or SF3P.
